To all whom 'it ma/J conce/rn.-

Be itA known that I, HENRY WOLFKILL, of Mill Creek Post Oice, Bradytownship, i11 tl 1ecounty of Huntingdon', and Stato of Pennsylvania,have invented a new and improved Velocipede; and I- do hereby de o larethat the following is a full, clear, andexactder4 scription thereof,which will enable others skilled in.

the art to make and use the same, reference being had to theaccompanying drawings, forming part of this specification, in whichfFigure l-represents a.r vertical longitudinal section of my'improvedvelocipede.

Figure 2 is a plan or top view of the same.

Similar letters of reference indicateA corresponding parte.

This invention relates to a new mechanism for pro-v pelling three andfour-wheeled ve l1icles,and also to certain improvements in thesteering-apparatus.

The invention consists chieiiy in the application of adjustablechains,'which transmit the ppwer to the driving-axle from thecrank-axle, with. the requisite degree of speed.

The invention also consists in so'notehing the steeri'ngelevers thatthey are held in place by their guides when not used.

A, in the drawing, represents the frame of my im-` proved vehicle,supported by the' front axle B and rear axlev C, each carrying asuitable numbenof wheels D.

The' frontaxle swings ou a king-boit, a,- and has leversE E extendingtowardthe seat F, which levers lit through staples,A b b, tt-ed upon'thelfraxne. The levers E are notched where they passitlir'ough `,thestaples, as shownand are by these notches locked., I When to beoperated, they must first, by la latein I mptiolnbe .released from thesta-ples, and can theiry be readily moved to steer the device. 1

. l G is the propelling-crank shaft, which is to be turned by hand.-vAOn it is mounted a double pulley, o el, one

'larger than the other. Above the front axle is arranged, .on the frame,a shaft, H, oarrying also two 'pulleys f, o ne smaller than the other,whlletwo 'smaller pulleys g hv areon the shaft C.v

A chain, '1, tted around the pulleys c e, will trans'- mit motion from Gto H, while another longer chain, J, transmits mtou from G to C, beingfitted around f and It In this manner the velocity is increased as-the ichains pass from the larger to the smaller' pulleys.

But more power, with less velocity, willbe gained by shifting the chainsor the pulleys, to have them pass. from the smaller to the larger. Orthe chain'J canv be entirely dispensed with, and the 'chain I be carriedfrom the shaft G directly to O.' The pulleys mayalso- 2.
